The time of day consists of an hour, minute, second, and time zone. Integer values can be used to represent the hour (0-23) and minute (0-59). Seconds can be represented using a decimal value depending on how often the time is updated (for example, every millisecond). The time zone can be represented using a string. So for example, 2:30 p.m. Eastern time is 14 hours, 30 minutes with a time zone of \"EDT.\" The seconds are not noted here, but will be a value between 0 and 60-for example, 03.120 is 3 seconds and 120 milliseconds.

a. Write specifications for a method that advances any given date by one day. Include a statement of purpose, the pre- and postconditions, and a description of the parameters.

b. Write a Java implementation of this method. Design and specify any other methods that you need. Include comments that will be helpful to someone who will maintain your implementation in the future.
